Selling a g&p mk18. G&p vltor stock, dd mk18 rail in bronze, full shs internals except for g&p 18:1 gears, shs ht motor, new hopup chamber and tbb. Has a feeding issue for the first few rounds of a mag, most likely due to the hopup chamber not staying put. Full metal upper and lower, free float outer barrel. Buyer pays shipping and PayPal fee, I will only accept trades if you are in Hawaii (kapolei, Waipahu, mililani, pearl city, etc). Shoot me an offer price wise, no lowballs.
